Benefits of technology

[0005]The mobile communication device is also required to have Bio-Compatibility; that is, lower SAR (Specific Absorption Rate, SAR) and HAC (Hearing-Aid Compatibility, HAC). One of the solutions is to dispose an antenna on the bottom of the mobile communication device. However, there is usually a data transmission interface for transmitting or receiving data on the bottom of the mobile communication device. The data transmission interface significantly impacts the performance of the antenna.

Problems solved by technology

The data transmission interface significantly impacts the performance of the antenna.

Abstract

A mobile communication device for operating in LTE and WWAN bands is provided in the invention. The mobile communication device includes a system circuit board and an antenna. The system circuit board includes a system ground plane. The antenna includes: an antenna substrate, substantially parallel to the system ground plane; a first radiation element, disposed on the antenna substrate; a second radiation element, disposed on the antenna substrate; an antenna ground plane, disposed on the antenna substrate, and coupled to the system ground plane; and a transmission line, disposed on the antenna substrate, coupled to the first and second radiation elements, and having a feed point. The mobile communication device is further configured to accommodate a data transmission component.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The disclosure generally relates to a mobile communication device, and more particularly, relates to a mobile communication device operating in LTE (Long Term Evolution) and WWAN (Wireless Wide Area Network, WWAN) frequency bands.[0003]2. Description of the Related Art[0004]Nowadays, 2G or 3G communication system technology is applied in notebooks, tablet PCs or mobile phones. Telecommunication manufacturers all over the world have actively introduced 4G LTE (Long Term Evolution) systems. Therefore, it is required that in small spaces, an antenna can operate in LTE and WWAN (Wireless Wide Area Network, WWAN) frequency bands.[0005]The mobile communication device is also required to have Bio-Compatibility; that is, lower SAR (Specific Absorption Rate, SAR) and HAC (Hearing-Aid Compatibility, HAC). One of the solutions is to dispose an antenna on the bottom of the mobile communication device. However, there is usually a da...
